The black-headed night monkey[1] is a nocturnal monkey species native to South America. The monkeys are small primates about the size of a small squirrel.
- Their coats are thick and short. The adult Aotus nigriceps has dark gray-black agouti fur on the upper back and front legs and orange-tan fur on the tail, outer hind legs, and lower back.
- They also have three distinctive black bands that almost converge on the forehead.
- Two of these bands follow the sides of the face to the upper jaw, with the central band extending to the bridge of the nose.
- In addition, they have white patches above each eye, under the mouth, and on the cheeks.
